John,
According to the weekly ANS report:
VO-52
V: LHCP
U: RHCP
That having been said, it is always desirable to be able to switch the
polarization. While the best signal, often by a wide margin, is found with
the published values, there are often times where with geometries far off
axis that the opposite polarization is significantly better. I have found
this over a wide range of satellites.
